Abstract: The invention relates to a forest machine, comprising a chassis having sides, a swing bogie mounted on bearings to the chassis, comprising a swing frame, second sides and at least two wheels, a swing bearing attaching the chassis to mount the swing bogie, a power transmission arranged through the swing bearing in connection with the chassis, a support formed by two pairs between the chassis and the swing frame, each pair having a protrusion as a support surface and a rail as a counter surface to transmit lateral forces between the chassis and the swing frame during contact between the two surfaces, wherein each pair is located at a distance from the swing bearing on separate side of the swing bearing, and in each pair, one of the protrusions and the rail is attached to the side of the chassis and other to the second side of the swing frame.

Abstract: A vehicle is structured for exerting a force on a dolly to move the dolly along a ground surface includes a locking pin mechanism having a locking pin, and a dolly tongue receptacle coupled to the locking pin mechanism so as to be movable with respect to the locking pin mechanism to a first position and a second position. A switch is coupled to the dolly tongue receptacle and structured to be operated by movement of the dolly tongue receptacle from the first position to the second position. The locking pin mechanism is structured to extend the locking pin into an opening formed in the portion of the dolly tongue responsive to operation of the switch.

Abstract: A retrofit assembly for conversion of a wheel driven vehicle to track drive, the vehicle having an undercarriage and left and right final drive mounts, the assembly incorporating left and right setback arms attached to and extending rearwardly from the vehicle's left and right final drive mounts; a “U” bracket having left and right “U” arms, the “U” bracket being fitted for laterally spanning the vehicle's undercarriage, wherein distal ends of the left and right “U” arms are fixedly attached to rearward ends of the left and right setback arms, and wherein forward ends of the setback arms are fixedly attached to the vehicle's left and right final drive mounts; left and right final drives respectively fixedly attached to the rearward ends of the left and right setback arms; and left and right sprocket driven tracks, wherein the track's sprockets are fixedly attached to the left and right final drives.

Abstract: An omega flex sway pod vehicular apparatus, comprising a cockpit and a cantilever beam comprising a first and second ends. A cantilever beam stabilizer centrally coupled to the cantilever beam proximate to the first end. A beam stiffener coupled to a beam stiffener mount and the cantilever beam and positioned proximate to the cantilever beam stabilizer. A spring coupled to a spring mount and the cantilever beam and positioned proximate to the second end. The cockpit is a hollowed, ovoid-like shaped structure. The first end is coupled to a cantilever beam mount. The body is demountably coupled to the second end. The beam stiffener mount is coupled to a snowmobile tunnel that includes a left and right side. The cantilever beam mount and spring mount is coupled to the snowmobile tunnel. The cantilever beam mount is positioned proximate to the front side.

Abstract: An apparatus fitted onto the forks of a forklift assembly for moving trailers, wherein the apparatus includes a right and a left rectangular tubular sections that are large enough to accommodate a fork. The sections are joined with a spanning beam having a center mounted trailer ball. The spanning beam is welded to the right and the left sections. A clamping element is mounted on a top wall of each section proximate to the rear of each section. Leveling elements are frontally affixed partially occluding an upper front opening of each section, such that tips of a fork are wedged under the leveling element and projecting beyond the front opening. Tightening the clamping elements secures attachment to the forks preventing the apparatus from sliding or rocking.

Abstract: A foldable cot including a base attached to a first end and a second end and side-bars connected between the first and second ends above opposite sides of the base, with the first side-bar 0 positioned further from the base than the second side-bar, and the side-bars hinged such that they may fold toward one another, and the base hinged so that it may fold towards the first and second side-bars, such that folding of the base causes folding of the side-bars, with the cot moveable between a first configuration in which the base, first, and second side-bars are substantially un-folded, into a second configuration in which the base is folded in the direction of the first and second side-bars, the first and second side-bars are folded such that the first side-bar folds above the second side-bar, and the first and second ends are brought together with the folded base and the folded first and second side-bars between them.

Abstract: A collapsible playpen includes an upper frame assembly, four standing legs and a bottom linkage assembly. The upper frame assembly includes a first and a second side opposite to each other that respectively have a first and a second coupling bracket. The four standing legs have lower end portions respectively provided a plurality of foot members. A first and a second standing leg are respectively coupled with the upper frame assembly via a first and a second leg linkage that are assembled with the first coupling bracket, and a third and a fourth standing leg are respectively coupled with the upper frame assembly via a third and a fourth leg linkage that are assembled with the second coupling bracket. The bottom linkage assembly is connected with the foot members of the four standing legs.

Abstract: A portable head support includes an upper portion having a top surface and a lower portion having a bottom surface. The top surface includes a first lobe portion at one end, a second lobe portion at an opposite end, and an intermediate or shaft portion separating the first and second lobe portions. The intermediate or shaft portion has a height, HI, and a length, LI, with respect to the bottom surface and the first and second lobe portions each have a height, H2, and a length, LL with respect to the bottom surface. The height, H1, and the length, LI, of the intermediate or shaft portion are less than the height, HL, and the length, LL, of the first and second lobe portions. The bottom surface includes a groove for allowing the portable head support to be mounted onto an object.
